SPARKING IGNITER.

Specification of Letters Patent,

Patented June 26, 1906.

To (1U 1071/0771, it' may concern:

Be it known that I, CHARLES M. HUEY, a citizen of the United States, anda resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Sparking Igniters, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle so as to distinguish it from other inventions.

My invention relates to electrical ignition devices, and particularly tothat class of such devices in which the parts thereof are readilyreplaceable and also interchangeable upon different machines; and itconsists of 'means hereinafter fully described.

'The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting but one of various mechanical forms in which the principleof the invention may be used. A

In said annexed drawings, Fi re 1 represents a central verticalsectionalliriew of my improved igniter. Fig.- 2 represents a horizontalsection of the same, taken upon the Fi 3 represents a front view o f thearmaturplate; and Fig. 4' represents a horizontal section taken upon theplane indicated by the line 4 4, Fig. 1.

In my improved igniter an outer protecting gas-proof casing A isprovided, having a hexagonal-shaped cover A', adapted to be dirt and gasproof and yet allow of easy access to the working parts of the device.The gas-tight casing enables the igniter to be used under water and insimilar submer ed places. vA core'or spool Bis containedwit in thecasing, is internally screw-threaded at its lower en and adapted toreceive an externally screw-threaded portion A3 of a plug A2, whichlatter is screwed into the cylinderhead, as shown. The plug A2 has acentral bore c', which receives a vertically-movable drill-rodor'bron'ze rod C, which projects Vinto the cylinder from such plug A2and extends centrally up through the core B and projects from the samethrough a plate C, suitably secured at the top thereof, as shown. Thisdrill-rod C is preferably made of non-magnetic material, so that it willnot grip when 'the core B is magnetized, and is adjustable Within thecore at c, the adjustability being secured by breaking the rod at c intotwo parts and threading one part intov the other. The inner part may bethreaded into the other part a greater or less amount, as is desired,from the outside of the core by operating the upper part of thedrill-rod after breaking its connection with a rocker-arm c2, to behereinafter more fully described. A

.suitable spring c is provided between a shoulder upon one of the partsof the drill-rod C at c and the top of the plug A2, which springoperates to normally hold the drill-rod C in its u permost position.

Suitab y pivoted to the top ofthe drill-rod C is a rocker-arm c2,comprising a right-angular piece pivotally mounted within its rightangle at csupon the plate C" and receiving at its top a pin D, which isscrew-threaded at its outer .end for a urpose hereinafter described. Aspring d) upon the pinD, disposed between the headl of the same and therocker-arm c2, acts as a cushion to take up any jar that might beoccasioned when the device is operated, as will be hereinafter fullydescribed. The plate C is provided with two upwardly-projecting ears c4,which receive a pin passing through the rocker-arm c2.at c3 to securethe rocker-arm pivotally to'A the plate C. An armature E is securelyfas' tened to the core B by short pins or screws e, passin throughsuitable ears e', and is normally eld out of contact'with the core B bymeans of a wire e3, passing around the core B, as shown in Fig. 2, andcomprising springs e2. These springs e are ends of the wire epass aroundpins e and extend rearwardly along the lateral ed es ofthe armature E,and at their tops are lent forwardly and crooked'so asto engage saidylateraledges ofthe armature, exert a pressure thereon, and normallyhold same out of contact with the core B. These springs e2 are made ofphosphor-bronze or other suitable non-magnetic material which willwithstand a great heat. The springs ma ,however, be made of magneticmaterial, if esired, and suitable nonmagnetic Wash ers provided on thepins e e.

The length of the springs e2 and the amount With vwhich they are bentforwardly and crooked maybe varied in order to vary the force which theyexert on the armature E.

The springs e exactly center the armature E relatively .to the core Band enable it to strike said core correctly when attracted thereby. Thelower part of the armature E is held only a short distance comparativelyfrom the core B,is tirst attracted by sa'd core, and then assists inpulling the upper part in toward the core. The armature is positioned acomparatively large distance vertically from the flange b of the core Bin order that said lange may not attract it and cause it to hang, sothat it would not be easily and readily pulled inwardly at the top. Themain portion of the armature is of substantially the same height as thecore B and at its top is provided with an upwardly-extending tongue je",which has a threaded bore adapted to receive the threaded end of the pinD,`which'rnay be threaded into the armature a greater' or less amount tovary the distance at which the armature is held away from the core B. ll

The drill-rod C receives at its lower end a transversely -locatedlconductor F, which passes through a small ring f, connectedt'o thedrill-rod, within which it is loosely upported and in which it has' alimited sli ing movemeht when the drill-rod C is operated, therebyehahlii'ig the conductor Epto move relatively to the rod C. Thisrelative movenieht 'of the conductor F and rod C ehables thecontact-electrodes f f2 (hereinafter described) to be kept ah'nernent'and prevents their beingv thrown around at an angle rto each 'otherwheh the rod C is operated. The conductor F-is provided at one end witha'. suitable contact electrode j", adapted yto form one of theelectrodes between which the spark passes to cause the desired inition.At, its other end said arm F is pivote: in the outer end of a conductorF', screwed into the lug A2. The plug A? isprovided with a arge bore K,laterally of its center and eX- tending up through ythe main portion ofthe saine. This bore is filled with suitable insu;- lating material 7c,which has a small central bore le', as shown; The lower flange b of thecore B is provided with a similar bore K/ laterally of its center andalso laterally of the bore K. Suitable insulation k2 with a bore lc'isprovided for the bore K similarly to the bore K. The bottom of thespool-flange l) and the top of'the main portion of the plug A2 areprovided with similar registering aniru'lar coves l1 b2, lilled withsuitable insulatklo from the winding of the core B. 'lhe central bore l"in the insulating material K is enlarged at itslower portion andreceives a conductor F2, provided at its outer end with acontact-electrodefz, adapted to form the second ot' the electrodes,between which the spark passes. The conducting-wire lvlis connected tothe conductor F2. The insulating-bushings 7c4 t' are sernicircular,grooved in their lateral centers, and reversely placed with respect toeach other, so as to form an annular tubular bushing in the registeringcoves b b2. Within the grooves in the littoral ceiiters yof this bushingare provided thin juxtaposed vcopper rings le k7, as shown. Theconductin'gwires le and k1" are connected to the rihgs k7 7c,respectively, and the current passes from one ring to the other-at anyof the contacting points upon their juxtaposed surfaces. Said rings arecompletely surrounded by the are nular cylinder of insulating materialfrine'd by the insulation 764 and 7c3' and thereby all short-circuitingis 'eli'ec'tively prevented. A binding-post a is secured to' the caslhgA 'aiid connected with one of the poles of the souree of electricity. ,I

The operation of the device, which `will be easily understood from theforegoing' de# scription, is as follows: The lcore B is magnetized bythe current passing 'around it in the winding, as shown, and attractsthe armature E, the upper end of which carriles '1n'- wardly with it thepin' D, which aetuates the lower end of the arm c2 downwardly and causesthe drill -rod C to carry the contact-electrode f away fromcontact-electrode f2 and produces a spark; This breaks the eirfc'iilt,which causes the core t'o release the armature, and thecontact-electrodesf and2 are aga-ih brought im@ jumps-sean. a will seread that the spring d protects the device from ahy jar when thearmature lies back to its noi"- mally outer position away from the coreB; The s 'arki'ng is very rapid, there being produce about seventy-rivesparks a second, producing4 a substantiall 'cotini'o'hs spark about thesi'z'e oi an or inary matcheheald; It will be noted that there are threeways el adjusting the armature so as to secure' vaniation' in thestrength and duration of the spark, which are respectively theadjustable joint at c on the drill-rod C, the adjustability ofthe outerend of the pin D within the arma'- ture E, and the variation of thetension of the springs e2. The adj ustability of the rod C also enablesthe contact-electrodes f and f 2 to be drawn more closely together whenthey have become worn. By means of this plurality of adjustments theforce withv which the armature E is held'away from the core B can be-nicely and accurately secured as is desired, it being readilyunderstood that the farther the armature is held normally from the corethe larger will be the spark 'that is obtained. .The center of the threeholes in the bottom of IOC in a the plu which receive the conductor F',the drill-ro C, and the conductor F2 ,lie in a straight line in the samevertical plane, thereby producing a moreefective device than thosedevices in which one of the outer holes necessarily lies off the centerto allow for-the operation of the eccentric hammers which are usuallyutilized. By providing the annular copper disks k k7 an accurate'adjustment orizontal plane does not necessaril have to be effectedbetween the screw-threa ed portions of the plug A2 and the core B, forcontact at a plurality of points will always be effected between thesedisks, because of the large contacting area with which they areprovided, and it will make no diiference in what vertical plane any partof either of the disks falls when the core B and the plug A2 have beenaccurately screwed together, for there will always be plenty of contactbetween the disks to satisfactorily conduct the current.

All of the parts of my device are interchangeable and can be used upondiiierent machines to which it is desired to attach them. Also each partis easy of access, so that if it becomes worn or if for any other reasonit is desired to replace it with a new part this may be done with verylittle difficulty. EX- terior to the igniter there is shown a diagram ofone suitable form of a circuit making and breaking device, asrepresented at H.

Because of the few parts of the device which it is necessary to operatein order to produce a spark and because of the ease with which theseparts are actuated a decidedly less amperage is required than in otherdef vices with which I am acquainted, and the saving of the cost of twoor three batteries is effected.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, 'provided the means stated by any'of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention- 1. In a sparking igniter, the combination of a casing; acore; an armature; a plug connecting the core and the cylinder-head; acontact-electrode secured to said plug and insulated therr rom; circuitconnections; a rod carrying a second contact-electrode; means connectingsaid rod and one end of said armature; and a spring intermediate of saidcere and the other end of said armature and constructed to bear againstthe lateral ed es of the latter, said spring thus centerin e armaturerelatively to the core and .ho din the same normally out of contact withsai core.
